In current wireless standards like 3GPP LTE or IEEE 802.16 / WiMAX multiple access is based on orthogonal signalling using single-carrier frequency-division multiple access (SC-FDMA) or orthogonal frequency-division multiple access (OFDMA). Links between a base station and different terminals use mutually orthogonal radio resources. This paper studies potential gains in average cell throughput by...
This paper describes the behaviour of electrostatically deflectable polysilicon torsional micromirrors. The electrostatic behaviouris computed by coupling of mechanical and electrostatic calculations using the FEM program ANSYS. Dynamic deflection measurements on a realized micromirror confirm the results of the simulation. In addition, the dynamic damping behaviour of a polysilicon torsional micromirror...
